Title: Improvements in or connected with locks
IPC: E05B27/00
Filed: 1926-11-05
Abstract: 286,341. Roberts, R. C., Smith, F., and Hook, C. J. Nov. 5, 1926. Lock mechanism, operated by non-rotating key; key, retaining until bolt is operated ; locks operating signalling apparatus; latches, sliding. - A lock has a part 6, which may be the bolt, moved rectilinearly by direct rectilinear pressure of an inserted key, after the key has, by insertion, released pin-tumblers 17 carried by the part 6 and an adjacent part. The bolt 6 has an elongated recess 10 to receive the key, Fig. 4, and is directly in line with the keyhole 2. It also carries projections 13, 14 mounted on a blade spring 11 so that unless the key with the correctly shaped and positioned recess 26 is used the bolt 6 cannot be thrust forward, even after the pin tumblers have been released, as the projection 13 will be thrust backwards by the key to bring the projections 14 into the path of the fixed projections 15. The key is kept in the lock by the projection 13 till the bolt is released. In applying the invention to a door, a latch 32, Fig. 9, with a forked inclined end 34 is mounted in the plane of the door and the key-mechanism at right-angles to it so that a rod 38 attached to or integral with the bolt 6 can operate the latch from outside the door. A knob 37 may operate the latch from the inside. An electric bell-operating device is incorporated with the lock. A push button 45 projects from the front plate 1, Fig. 1, of the lock and has a rod 46 connecting it to a plate 46<x> carrying a pin 47 extending through the lock case. The bell may be directly operated by the push button or by the movement of the block 7 carrying the fixed pins of the tumblers 17 due to the insertion of a wrong key, the block having a slight freedom of movement longitudinally for this purpose. The bell may be an ordinary signal or an alarm signal. In the application of the device to locking motor vehicles, a bolt 57 may engage the fixed and rotating columns of the steering gear under spring pressure. Release is effected by an inclined member 6<a>, which is pushed downwards by the member 6 of the lock, to withdraw the bolt 57. This bolt may be held retracted by a sliding stop 60 engaging the lower part of the flange 56. A push-piece 59 protruding from the casing enables the stop to be moved out of the path of the bolt for ready locking of the steering column.

Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: H02P23/16
Filed: 1958-09-01
Abstract: 892,487. Electric control systems. BOSCH G.m.b.H., ROBERT. Sept. 1, 1958 [Sept. 18, 1957], No. 27925/58. Class 40 (1). [Also in Group XL (c)] Electric apparatus for controlling the quantity of fuel injected into the cylinders of an I.C. engine in accordance with the speed of the engine, the ambient temperature and pressure, and the temperature of the water in the cooling system, comprises two monostable transistor relaxation oscillators in cascade containing resistors sensitive to the various non-electric quantities, which determine the duration of the unstable condition of the oscillators during which time a valve in the fuel supply pipe to the cylinders is opened. As shown (Fig. 1) the first relaxation oscillator comprises two transistors T1, T2; T1 being normally non-conducting and T2 conducting. When switch S is closed by rotation of cam N driven by the distributer shaft 11 of the engine 10, the base potential of T1 is lowered causing T1 to conduct and block T2. This unstable condition reverts when the potential across condenser 58 is sufficiently reduced by discharging through parallel resistors 59, 60, the former having a value determined by the ambient temperature and pressure. The duration is also controlled by D.C. voltages across resistors 65, 66 connected to the base of T2. The former resistor is fed with part of the rectified voltage generated in winding W1 of a generator G driven by shaft 11, the slider of potentiometer 73 being mechanically linked to the throttle pedal F, thereby tapping off a smaller voltage at higher speeds; resistor 66 is fed with the rectified voltage generated in winding W2 of generator G. Thus the duration of the pulse in the relaxation oscillator is determined by the ambient temperature and pressure and by the engine speed. The second relaxation oscillator similarly comprises two transistors T3, T4, the latter being normally conducting. The negative pulses developed on the collector of T1 are fed to the base of transistor T3 to make it conduct and block T4, the duration of this unstable condition being determined by the discharge time of condenser 78, and the value of resistor 80 which is a negative temperature coefficient resistance, sensitive to the temperature of the engine cooling water. Hence the base of an output transistor T5 receives a pulse from the first oscillator which is extended by a pulse from the second oscillator when the engine is cold, which pulses produce collector current in T5 flowing through the coil 34 of valve 33 to open the valve and allow fuel to enter the engine cylinders for the duration of the pulses.

Abstract: 973,518. Nut tapping machines. W. LOOS. July 23, 1962 [Aug. 1, 1961], No. 28180/62. Heading B3N. A nut tapping machine comprises a slider 1 actuated by a cam 4, a curved shank tap 6, a supply shoot 7, a scanning pin 9 carried by the slider, a main drive switch 13 actuated by a cam 12, and a second main drive switch 15, actuated by a cam 14. In operation, slider 1 pushes a nut on to rotating tap 6 with switch 15 switched on. Pin 9 orientates a subsequent nut 8 in the shoot, and the first nut is tapped. Switch 15 is switched off by cam 14, and subsequently switch 13 is switched on by cam 12 being forced against spring 16. If pin 9 cannot pass through a nut in the shoot, switch 13 is not actuated, and the machine is stopped. If a tap breaks, slider 1 is blocked, switch 15 cuts off the circuit, and switch 13 is not switched on, and the machine is stopped. A toggle switch is provided in the circuit to bridge switches 13 and 15 for starting the machine. An acoustic, or optical signal comes into effect when the machine stops.

IPC: D04H1/645
Filed: 1969-06-04
Abstract: 1278642 Heating platen presses; laminates FIBREGLASS Ltd 27 May, 1970 [4 June, 1969] 28289/69 Headings B5A and B5N. [Also in Divisions D1 and H5] A glass fibre mat coated with phenolic resin is pressed between plates 35, 41 whilst the resin is heat cured. The plates are maintained at a temperature of 400 F. by resistance heaters 28, to raise the surface of the mat to at least the minimum curing temperature, whilst the centre of the mat is raised to a higher temperature by dielectric current produced by high frequency voltage applied to plates i.e. electrodes 35, 41 by circuit 50. Contoured products may be produced by shaped electrodes. A laminate is produced by placing on the lower electrode 35 an aluminium foil coated on its upper surface with polyethylene, followed by a glass fibre mat coated with phenolic resin and pressing whilst the upper electrode was heated to 400 F., the lower electrode to 310 F. and dielectric current passed to cure the interior of the mat. Both surfaces of the mat may be bonded to a facing material (Fig. 5, not shown), and later the mat and the facing material may themselves be laminates, the laminations preferably being carried out simultaneously. The apparatus comprises four vertical rods 18, upon which slide the upper and lower frames 16, 17. Asbestos blocks 43, 44 and sheet 47 insulate platen 40 from frame 16. Electrical resistances 28 heat platen 40 and thus upper aluminium electrode 41, and likewise lower platen and electrode 24, 35. Whilst upper frame 16 is normally clamped in position, lower frame 17 is moved by hydraulic jack 23 between limits set by sleeves 21, 22. Several small mats may be placed on lower electrode 35 to be cured simultaneously. Continuous curing of a coated mat is achieved by passing it between endless conveyer bands formed with non-ferrous material which act as electrodes, or alternatively the conveyer bands pass between fixed electrodes.
